As big as a Galaxy Note 8, maybe. Which, according to another post, looks like a gigantic phone.

Yay. Phones for giants.

I’m not talking about overclocking. I’m talking about binning done at the fab.

Lol. Reminds me of Dana Carvey and The McLaughlin Group, “Wrong!”. Patty Patty Buch Buch.

That would be unstable. The higher the clock speed, the higher the voltage required to maintain that speed.

Why would voltage go up? Wouldn’t they just bin the higher clocked dual core at the same voltage and current?

Not much. The overhead of spawning and synchronizing threads is overcomed if the processing maxes out the cores for a prolonged amount of time. Since mobile apps usually just burst CPU usage you won’t really notice any performance differences between 2 or more cores of the same architecture. Also, not all processing can benefit from multi-threading anyway.

Also, in terms of heat dissipation, it’s easier to clock a dual core higher than a quad core since the thermal design of a device should be able to dissipate the heat when all cores are actually active without causing thermal throttling.

Unless you have several background or foreground apps that taxes the CPU simultaneously then throwing more cores on a device won’t have much advantage.

Wrong. Mobile applications either support one core or multi-core. So there are still many that will support 8 cores or even 500.

I’ll hide under the covers, wear mascara, and cry all night into a camera, yelling at the internet for not leaving you alone, Tim.

4 cores at 1.5ghz uses less power than 2 cores at 2.5ghz (for most architectures). Speed scales with voltage, and power scales exponentially with voltage.

So no, that 4 core arrangement inherently uses less power, and it also has the ability to programatically shut down and start up cores when needed which adds an even larger advantage.

damn that chip is bigger than my hand…how huge are these devices gonna be?!?!?!

Its only quad core, its simply has two power states using different sized chips. It’s really a quad-core cortex a-15 which makes it a much faster version of last years chip.
